Senate Minority Leader Mitch McConnell is among those calling for Pelosi to reconvene the House early.

WASHINGTON (CNN) -- Leading Senate and House Republicans urged House Speaker Nancy Pelosi, D-California, Monday to call the chamber back into session "immediately," in order to move a House and Senate-backed Iraq spending bill to the president "as quickly as possible."

Both the Senate and the House have passed versions of a spending bill that include a withdrawal deadline. Differences between the two measures have to be ironed out by both chambers before the bill can be sent to President Bush. Bush has vowed to veto any bill that includes a withdrawal deadline.

"We are writing to urge you to call the House back into session immediately so that Congress can finish its work on the emergency legislation to fund the Global War on Terrorism," the congressmen wrote in a letter to Pelosi dated Monday. "This funding request has been pending since February 5, but your leadership team chose to leave town for more than two weeks rather than completing this bill. As a result, our troops have been put at risk."
